The photo, of them as a much younger couple, was captioned, “Feels,” sending his fans into spasms of emotions themselves.
Though Bieber, 22, and Gomez, 23, last split in 2014, after being on-and-off since 2011, they’ve stayed connected.
The two spent time together at a hotel bar in Beverly Hills, California, in November, where Bieber serenaded her with both the classic “My Girl” and his hit “Sorry.”
In December, Bieber again publicly reminisced about their relationship with another image of them as a couple, this time of the two holding hands, with the caption, “Crazy throwback.”
“I’m proud of the woman she is today,” Bieber told Billboard in a November cover story. “When you love someone that much, even if something comes between you, it’s a love that never really dies.”
Or as one source close to the singers told PEOPLE in November, “They care about each other and miss each other, but they’re not getting back together right now.”
